New Balance, which is building a new $500 million headquarters complex in Brighton, added to its property holdings there this week with the more than $10 million purchase of another Guest Street property.

The Hub athletic footwear and clothing company bought the approximately 2.5-acre property at 125 Guest St., the site of a reprographics company.

“This property was a good opportunity to aggregate additional square footage that serves as a gateway parcel to our current Boston Landing development,” spokeswoman Amy Dow said. “At this point, we do not have specific plans for the property.”

New Balance broke ground in September on Boston Landing, next to its current headquarters and WGBH Boston. In addition to its new 250,000-square-foot world headquarters, the 14-acre Guest Street development will include a 175-room hotel, three office buildings, shops and restaurants, and an extensive athletic complex along the Massachusetts Turnpike.

The sports complex will include a professional hockey rink, a 200-meter hydraulic track, three basketball courts, a fitness center, and office and retail space.
